TL;DR: Red or bleeding gums in cats usually indicate dental disease and require a veterinary exam within 24–48 hours. Seek immediate care if your cat stops eating or shows signs of extreme lethargy and pain.
What causes my cat to have red, inflamed, and bleeding gums?
Red, inflamed, and bleeding gums in cats are primary indicators of dental disease. Common causes include:
- Gingivitis caused by plaque and bacteria buildup along the gum line.
- Feline stomatitis, a severe immune-mediated inflammatory response.
- Fractured teeth or oral resorptive lesions.
- Oral tumors or systemic conditions such as kidney disease.
Are bleeding gums in cats considered a veterinary emergency?
The urgency level for bleeding gums is categorized as Medium. While rarely a life-threatening emergency in the immediate moment, it indicates significant pain. You should take the following actions:
- Schedule a veterinary appointment within 24 to 48 hours to manage infection and pain.
- Seek immediate care if your cat has completely stopped eating.
- Contact a vet urgently if your cat is pawing at their mouth aggressively or appears extremely lethargic.
How can taking a photo of my cat's mouth help with veterinary triage?
Taking a clear, well-lit photo of your cat's gums can be incredibly helpful for a veterinary professional for several reasons:
- A photo taken in a calm environment allows the vet to see the exact location of redness or ulcers without stressing the cat.
- It helps the vet identify suspicious growths that may be difficult to see during a physical exam.
- Visual evidence helps determine if the issue is localized to a single tooth or requires more intensive, widespread intervention.
Clinical Context (Merck Veterinary Manual)
Feline stomatitis is a relatively uncommon but serious condition characterized by progressively worsening inflammation of oral mucosal tissues, particularly the gingiva, alveolar mucosa, labial and buccal mucosa, sublingual mucosa, and mucosa of the caudal oral cavity. Severe ulceroproliferative inflammation involving the area at and lateral to the palatoglossal folds bilaterally is pathognomonic for feline stomatitis. Affected animals may exhibit reddening and swelling of the gingival margins and interdental papillae that bleed easily, potentially progressing to gingival recession, ulcerated or necrotic mucous membranes, and exposed bone. Other signs can include halitosis, ptyalism (sometimes blood-tinged), anorexia, pawing at the mouth, and enlarged regional lymph nodes. Uremia and thallium toxicity, though rare, can also cause stomatitis and oral ulcers.
